Abstract

The present invention relates to a method of producing a continuous molding making use of an extrusion solution containing preferably water, cellulose and a tertiary amine oxide. The extrusion solution is extruded through an extrusion-channel opening so as to form a continuous molding. The continuous molding is conducted through an air gap in which it is drawn. In order to increase the non-looping property and in order to reduce the fibrillation tendency, the present invention is so conceived that the mean acceleration and/or the mean heat flow density are controlled in accordance with predetermined formulae.
